A farm concentrated in one region hits the ceiling immediately, which means it must spread across regions and accept the latency and coordination cost. Admission is capped at 13 identities per region per epoch, and the region is derived from the ledge attestation rather than declared. Repeating the trick 8 times costs 39 separate deposits and 12 separate proofs of work. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":2,"sig":"298JSZKQTt61V5kmdsMxv8GDXVPy1JeVJMqp1gipKPrVkz2q1h4dyXhj7VFhmCz8Tw3jzqh1cGXwqDTWLWUmZRQC"},"checkpointed":{"height":33314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:30:20.722Z","checkpoint_height":33314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
